PNG files are great for graphics, but a photo or a large screenshot saved as PNG can easily be 5–10 times larger than the same picture as a JPG. This converter turns PNG images into JPG so they upload faster, fit through email limits and are accepted by forms that only take “.jpg”.
Because JPG has no transparency, you choose which color fills the transparent parts (white by default). Add one PNG or a whole folder, set the quality, and download the JPGs individually or as a ZIP. The conversion happens locally in your browser, so your files are not sent anywhere.
How to use the PNG to JPG tool
- Add your PNG files by clicking Choose files or dropping them on the box.
- Pick a background color for transparent areas (white works for most uses).
- Adjust the quality slider. 85–92 gives a good balance of size and detail.
- Click Convert and compare the old and new file sizes.
- Download each JPG, or grab them all with Download all (ZIP).

When to convert PNG to JPG (and when not to)
Convert to JPG when the image is a photo or a screenshot full of gradients, when you need a smaller file for a website, email or online application, or when a site simply refuses PNG uploads. Social networks recompress images anyway, so starting from a JPG costs you nothing.
Keep the PNG when the image needs a transparent background (a logo placed on colored pages, a product cut-out, a sticker), or when it contains small sharp text and thin lines that must stay crisp. JPG compression can add faint blur and “ringing” around hard edges.
What happens to transparent pixels?
JPG cannot store transparency, so every transparent or semi-transparent pixel is blended onto the background color you pick. If the JPG will sit on a white web page or document, keep white; for a dark website choose a matching dark color so the edges blend in smoothly.
Frequently asked questions
Why is my JPG so much smaller than the PNG?
PNG uses lossless compression that keeps every pixel, which is inefficient for photos. JPG uses lossy compression tuned for photographic detail, so it can throw away information the eye barely notices and save a lot of space.
Why did the transparent background turn white?
The JPG format does not support transparency. Pick a different background color before converting, or keep the file as PNG or WebP if you need transparency.
Is PNG to JPG conversion lossless?
No, JPG is a lossy format. At a quality of 90 or higher the loss is very hard to see on photos, but text and line art may look slightly softer.
Is it safe to convert private screenshots here?
Yes. The PNGs are processed by your browser and are never uploaded, stored or seen by anyone else.
